A quick start.

We are going to step up into Physics, but what Physics is? Thus let's clear the picture from the beginning: - Physics is a science about the laws of nature. The laws of nature are derived from observations of nature. Thus a physicist is both observer and interpreter. The ultimate goal of physics is an accurate explanation of the observed phenomena ( thus we will need math) to predict the behavior of the object under study in a certain environment.

The object under study.

Our universe consists of matter and energy. Matter can be viewed as a specific form of energy - the conserved one. Material objects appeared as a result of transformations of some amount of energy after the Big Bang.
